ICP Furnace Parts

ICP Furnace Parts: Heil, Tempstar, Comfortmaker, Arcoaire & Grandaire

ICP furnaces — sold under the Heil, Tempstar, Comfortmaker, Arcoaire, and Grandaire brand names — share the same core engineering and parts across all five labels. Whether your unit is a mid-tier Heil or a builder-grade Comfortmaker, the igniter, control board, inducer motor, and pressure switch you need are often identical across the family. That cross-compatibility saves you money and simplifies repairs, but model number verification is still essential to confirm the exact part matches your unit's specifications.

When your ICP furnace won't ignite, runs but produces no heat, or cycles through error codes, the culprit is usually one of a handful of high-failure parts. Hot surface igniters fail after years of thermal cycling. Inducer motors wear out and trigger pressure switch errors. Control boards develop bad solder joints. Repair Clinic stocks genuine OEM ICP furnace parts for all five brands in the family, backed by expert model-number lookup and same-day shipping.

• Hot surface igniter: furnace clicks but won't ignite; orange glow that fades or doesn't appear
• Draft inducer motor: rattling noise, furnace won't start, or pressure switch keeps tripping
• Pressure switch: furnace cycles on and off, won't stay running; often a blocked drain hose or cracked inducer hose is the root cause
• Flame sensor: furnace ignites then shuts off within seconds; usually needs cleaning first, then replacement if that fails
• Control board (CNT/IFC board): no response from thermostat, error code flashing, or furnace dead; always verify voltage and safety interlock status before replacing

Use our ICP furnace parts page to enter your model number and find the exact replacement igniter, motor, switch, or board your Heil, Tempstar, Comfortmaker, Arcoaire, or Grandaire furnace needs.

ICP Furnace Parts: Questions & Answers

Are Heil, Tempstar, Comfortmaker, Arcoaire, and Grandaire furnace parts interchangeable?

Yes — all five brands are manufactured by ICP (International Comfort Products, a Carrier subsidiary) and share the same engineering platform. A Heil igniter, Tempstar control board, or Comfortmaker inducer motor will often fit the other brands in the family. However, always use your model number to confirm compatibility. While most parts cross-reference, some parts are model-specific. Enter your Heil, Tempstar, Comfortmaker, Arcoaire, or Grandaire model number to see the exact part that fits.

What's the difference between Heil, Tempstar, Comfortmaker, Arcoaire, and Grandaire furnaces?

Heil and Tempstar are mid-tier residential brands sold through HVAC contractors and dealers. Comfortmaker is the entry-level builder-grade brand. Arcoaire is a regional brand primarily found in the Southeast. Grandaire is a regional builder-grade line. Despite the different brand names and slight variations in cabinet style or control board graphics, the furnace operation, gas valve, burner assembly, heat exchanger, and safety interlocks are virtually identical. Parts sourced through Repair Clinic work across all five because they're all ICP-built on the same chassis.

How do I find my ICP furnace model number?

Your model number is on a metal data plate attached to the furnace cabinet, usually on the side or front panel. It begins with letters (e.g., HEH, TPK, CMC, ARC, GRA) followed by numbers. Write down the complete model number, along with the serial number if visible. Use our model lookup tool to enter that number and match it to the correct parts for your specific model.

Why did my ICP furnace suddenly stop igniting?

The most common culprit is a failed hot surface igniter. Silicon carbide igniters weaken over 10 to 20 years of thermal cycles — they glow dimly, or don't glow at all, and the gas valve never opens. If the igniter glows orange but the gas valve doesn't trigger, the igniter is failing. If the igniter doesn't glow at all, check for power at the igniter terminals; if power is present, the igniter is dead and needs replacement. A distant second cause is a bad control board losing igniter voltage output. Replace the igniter first (it's the cheaper, more common fix), then test. If the new igniter still doesn't work, suspect the control board.

ICP Furnace Model Number: Where to Look

ICP typically places the furnace model number on a metal data plate attached to the cabinet, often on the side or behind the front access panel.

Type it into our model number lookup and the catalog narrows to parts made for your unit.
